Filed: 1919-02-12
Abstract: 128,866. Starkie, R. E. Feb. 12, 1919. Table games; race games, mechanical.-A table game is played by means of representations a, h of aeroplanes or air-ships traversed by two handoperated screws 8 mounted in model structures 2, 3 clamped to the table. The propellers 21 are carried by extensions 20 terminating in wires 26 sliding within the body of the aeroplane, and holes are provided in the extensions and in the bodies so that when the propellers are pushed in the holes coincide and a ball cylinder or dart is dropped. A map or groundwork with two or more cups 30 is arranged beneath the screws. To facilitate rapid adjustment of the aeroplanes along the screws 8 the screwed holes through the suspending members 12 are enlarged in a vertical direction so that the screwed portions may be lifted apart. In playing one form of game, the two players each rotate a handle and the first player to traverse his aeroplane along the screw until contact of the propeller with the structure 2 drops the ball is the winner. When a number of cups 30 are provided each player traverses his aeroplane until over a cup and then discharges the ball by pulling out the wire 26, re-charges the aeroplane and continues the winding.

Patent GB-428559-A (GB)
Title: Improved method and means for coating a metallic surface with fusible material or substance
IPC: B05D3/02
Filed: 1934-02-03
Abstract: The metallic surface of a container is coated with fusible material, such as wax or resin, by spraying the molten material on to the surface and fusing the resulting powdery deposit, with subsequent solidifying, on cooling, into an even, thin coating. In the case of a small container, fusion of the powdery deposit may be effected by immersing and rotating the container in a bath of hot water, and, in the case of a closed container, the hot water may also function as a medium for testing the fluid-tightness of the container, if air under pressure is introduced through a hollow trunnion.  With a large container, the deposit may be fused by means of a blow-lamp. Reference has been directed by the Comptroller to British Specification 275,477, [Class 94], and U.S.A. Specification 1,869,630.

Title: Improvements in or relating to Reinforced Concrete Vessels and other Floating Structures.
Inventor: HILLIARD ALFRED WILLIAM
IPC: B63B5/16
Filed: 1918-02-28
Abstract: 123,595. Hilliard, A. W. Feb. 28, 1918. Concrete vessels.-A method of constructing reinforced-concrete floating structuxes without using shuttering consists in temporarily suspending a series of shaped vertical rods, connecting a series of horizontal rods and vertical stiffening bars thereto, covering one or both sides of the structure with expanded metal and applying concrete in one operation so as to embed the metal in a mass of concrete. The vertical rods, preferably in single lengths from the keel to the top of the deck coamings, are suspended from horizontal rods A shaped to the upper contour of the vessel and suspended by hangers B from beams c. A series of longitudinal rods b is secured to the rods a. and a further series of vertical rods c may be attached to the rods b, or they may be suspended in the same manner as the rod a. Two series of longitudinal rods may be used, and stiffening bars consisting of simple rectangular bars or of rods tied together, as shown in Fig. 5, or surrounded by hoops connected to the main framework, may be arranged behind some of the vertical rods. The structure is then covered with expanded metal d which may be corrugated and bent to include the stiffening members. Concrete is applied either by hand or by means of a blower or pump. The keel may be provided with a double floor formed by means of transverse and longitudinal rods, e.g. supported by vertical clips f, h from the main reinforcement and covered by expanded metal bent up and down to form a series of open rectangular chambers. The walls may have holes for drainage purposes, and may support a wooden or reinforced-concrete floor. The deck coamings may be supported by reinforced-concrete brackets.

Title: Retentive memory circuit
IPC: H03K17/24
Filed: 1961-01-31
Abstract: 939,272. Controlled non-linear inductors. SQUARE D CO. Jan. 31, 1961 [July 12, 1960], No. 3607/61. Class 40 (9). A magnetic amplifier having a core with remanent properties stores the output of a " NOT OR " transistor circuit regardless of power supply failures or interruptions. As shown in Fig. 4 the magnetic amplifier has a core 66 having a gating, a bias and a control winding 68, 70, 72, the bias winding 70, acting in the opposite sense to the other two windings. The gating winding 68 is in a circuit comprising an A.C. source 73, a half-wave rectifier 74 and a load resistor 82, the output voltage across the resistor when the core is saturated being sufficient to charge a capacitor 90, and to hold a transistor 84 in the conductive state so that the control winding 72 is energized. While all three windings are energized the amplifier remains saturated, and this saturated state is maintained when the source 73 is interrupted. The transistor 84 is initially brought into its conductive state by a negative potential at its base 84b which occurs in the absence of any input to the base of a transistor 36 included in a "NOT OR " circuit. To cut-off transistor 84 when the " NOT OR " circuit transistor becomes conductive due to a negative input at its base, the capacitor 90 is discharged by a transistor 112 which is rendered conductive by a negative potential from a further " NOT OR " circuit comprising a transistor 40. This de-energizes the control winding 72, and the magnetic amplifier operates in the unsaturated region so that negligible output is developed across resistor 82. Capacitors 126 and 128 are provided to prevent the transistors 112 and 84 from responding to unduly brief input signals. The output from transistor 84 is applied directly to terminal 100, and is also applied to a terminal 110 after inversion by a transistor 102. The latter output is also fed back over a resistor 124 to the base of transistor 84, and provides a path from a power supply smoothing capacitor 62 which delays the discharge of capacitor 90 when the supply is interrupted. Operating potentials of - 20 volts and + 20 volts on conductors 56 and 58 respectively are derived from a power transformer and rectifier circuit 34 which may include a secondary winding constituting the source 73.

Title: Improvements relating to aerial ropeways
IPC: B61B12/02
Filed: 1925-02-09
Abstract: 250,706. Main, G. A. Feb. 9, 1925. Rotary tipplers.-A tippler 1 for use with aerial ropeways is supported on wheels 2 carried by a beam 6 suspended from the traveller A. Normally the tippler is locked against rotation by a lever 8 pivoted on the beam and engaging a slotted flange 10 on one of the tippler rings. A flexible shaft 13 driven from one of the track wheels turns a screwed rod 12 so that at a given distance from the loading station a half-nut 11 travelling along the rod 12 strikes the lever 8 and releases the tippler. The tippler makes a complete revolution whereupon it is again locked by the lever 8, the nut 11 having meanwhile moved away as described below. The tippler may rotate by gravity, the body of the truck or the rails themselves being to one side of the axis of the tippler. To ensure a complete rotation, ball-bearings or the like are used to reduce friction and the centre of gravity of the empty wagon is arranged to lie on the axis of rotation. The half-hut 11 is carried by one arm of a lever 16, 17, Fig. 3, mounted on rollers on a square rod 18 parallel with the screwed rod 12. As the tippler rotates, a lug 15 on one of the rings strikes the lever 16, 17 and lifts the half-nut out of engagement with the screwed rod. The lever 16, 17 carrying the halfnut then slides along the square rod 18 by gravity or under the action of a cable until it reaches a stop. This stop may be adjusted so as to determine the distance the carrier must travel before the wagon is discharged. When the lever 16, 17 is turned aside by the lug 15 as just described, the rod 18 is held by a pawl 21<a> engaging a ratchet wheel 19 on the rod, but when the tippler returns to the loading station a stop 20, Fig. 3, engages the arm 21 of the pawl, releasing the ratchet wheel and allowing the rod 18 and lever 16, 17 to turn by gravity or under the action of a spring or weight, so as to re-set the tripping-mechanism with the half-nut 11 engaging the screwed rod 12.

Patent GB-824897-A (GB)
Title: New copolymers of vinyl chloride
IPC: C08F214/06
Filed: 1958-02-05
Abstract: New copolymers have vinyl chloride as the major component and, as a minor component (e.g. 0.1-5%), an organo-tin compound having a vinyl group attached directly to the tin atom.  Another organo-vinyl component, e.g. vinyl acetate, may be present in a smaller proportion than the vinyl chloride.  The organo-tin compound may contain besides the vinyl group hydrocarbon radicals other than vinyl, e.g. ethyl or butyl, and/or acyloxy radicals directly attached to the tin atom. The products are stable to light and heat, even with a low proportion of the tin compound. Copolymerization is preferably effected in emulsion in water containing a suitable dispersing agent, e.g. partly saponified polyvinyl acetate, and a catalyst, e.g. lauryl peroxide. Plasticization of a copolymer of monovinyl diethyl tin laurate with vinyl chloride, followed by hot calendering, gives substantially colourless sheets.  Fractional precipitation of the copolymer followed by an estimation of the tin content of the various fractions shows uniform copolymerization.

Title: Improvements in or relating to hydraulic rotary mechanisms
IPC: B60K17/10
Filed: 1955-02-09
Abstract: 778,425. Rotary engines &c. TRIPP, G. H. Feb. 9, 1955 [Feb. 9. 1954], No. 3855/55. Class 110(2). Hydraulic rotary mechanism comprises a stator and a rotor having spaced pockets along the periphery elongated in the direction of rotation and of tapered depth which pockets communicate with intake passages in the stator spaced from exhaust ports to which liquid is urged by abutments slidable in slots in the stator, liquid under pressure urging the abutments into the pockets of the rotor. Fig. 1 shows reversible mechanism for transmitting the drive from a motor to the shafts and comprises a housing 17 with extensions 18, 19 in which are mounted the shafts 20, 21 extending into a casing 25 and carrying differential gears 22, 23 meshing with an idler 28. The idler 28 is mounted on a bearing 29 carried by the casing 25, on which drive-rings 30, 31 are rotatably mounted. The ring 30 has a flange 32 which may be connected to the casing 25 by a clutch, Fig. 2. Balls or rollers 34 in the periphery of the casing 25 engage the flange 32 when a brake band 36 is tensioned by linkage 40, 44 to prevent rotation of the ring 30 relative to the casing. A similar connection is provided for the ring 31, the two clutches being arranged to operate in opposite directions. The clutches are housed in a stationary annulus 46 having inwardlydirected flanges 47, 48 and an extension 49 passing through the housing 17 and connected to a. tube 51, the tube being connected to a fluid source such as a pump driven by the vehicle motor. The passage 50 through the extension 49 has two branches connecting with annular passages 52, 53 formed by matching grooves in the annulus 46 and rings 30, 31. Intake ports 54, Fig. 5, lead from the passages 52, 53 to recesses 55 in the juxtaposed walls of the ring 30, 31, the recesses being tapered and arranged in echelon. Each recess receives a vane 57 axially slidable in the neighbouring ring. Thus fluid under pressure enters the recesses through the ports 54 and impinging on the vanes 57 causes rotation of the rings 30, 31 together with the casing 25, the direction of rotation being determined by locking the appropriate ring 30 or 31 to the casing. As the casing 25 rotates the gear 28 transmits the drive to the shafts 20, 21. Ports in the passages 53 admit fluid to the vane housings to press the vanes outwards and fluid from the recesses 55 is exhausted through ports 59, Fig. 5, into the housing 17 and is returned to the source through an outlet 60, Fig. 1. A modification is described which is applicable to the driving of industrial machinery, the drive being irreversible.
